GEORGE 1a. LARSON. or HONEYFORD. NORTH DAKOTA.

Beit known that I, Gsonor: M. Lansolv. a i citizen of the UnitedStatesresiding atl Honeyford. in the count v of Grand Forks State ofNorth Dakota, haveinvented certain new and useful Improvements inSwimming-shoes; and I do hereby declare the l following to be a full.clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to swimming shoes and has for its object toprovide a shoe ha ving lateral wings that will swing outward into theplane of the sole during the outward stroke and will swing toward eachother and enter within the borders of the shoe sole during the initialor gathering movement of the stroke so that no resisting surfaces willbe presented to the water durl ing this movement of the stroke.

in ordinary swimming shoes one disadvantage is that the wings projectbeyond the edges of the sole during the gatheringmovement of the strokeand present resisting; surfaces to the water which impede progress ofthe swimmer. To overcome this disadvantage I provide terminal axialextensions to the sole and further provide the wings with lateralextensions on their sole confronting edges which are terminally hingedto the sole extensions, this construc tion causing the wings to swingbodily in the direction of each other and lie entirely within theborders of the sole during the gathering movement of the stroke.

In the accompanying drawing forming part of this specification. Figure 1is a perspective view of the swimming shoe sh0wing the wings in positionduring the stroke. Fig. 2 is a pers 'iective view of the swimming shoeshowing the wings in position during the gathering movement of the strke. Fig. 3 is a view in elevation looking toward the tread of theswimming shoe sole with the wings in the position shown in Fig. i. l ig.'l' is a plan view of the shoe showing the foot engaging moccasin. Fig.5 is a. cross sectional view taken on the line 5 5 Fig. 3 with the wingsin elevation.

Referring now to the drawing in which like characters of referen edesignate similar parts in the views shown. 10 desi nates the shoe sole,the same being prelerablv formed of wood of a similar material and beingprovided terminally with reduced "Specification of Letters Patent.Application filed October 4,1910. serial No. 585.289.

axial extensions lljthe edges at the juncture of these extensionswiththe sole proper b eingrounded as shown at- 12. Secured to the sole. is amoccasin 13 formed of leather or other suitable material, and havingheel 1 straps 14 which pass over the instep and secure the shoe to theswimmers foot. Connection of the moccasin with the sole maybe made bybrads or similar connectors 15.

Arranged on the opposite sides of the sole is a pair of wings 16. eachwing preferably formed of wood or similar material of the same thicknessas the sole and having its sole confronting edge 17 conforming to theoutline of the marginal edge of the sole, and further having its1outeredge curvilinear in outline as shown iii-Fig. 4. Arranged adjacent theopposite ends of each wing is a lateral projection 18 which conforms tothe outline of the curved portions 12 of the sole the sole extension 11.Arranged on the tread surface of the sole extension 11 and correspondingsurface of each adjacent wing extension 18 is a hinge 19. and it will beobserved that by virtue of these hinges the wings are movable towardeach other and when in this position both wings will l1e"en-' tirelvwithin the borders of the sole 10 as clearly shown in Fig. 2. Thus thewings feather during the gathering position of the stroke and when infeathered position present no resisting surfaces to the water toim-.pcdethe movement. of the swimmer. The wings are preferahh formed withtheir outer edges curved in the same direction from the plane of thesole as shown at 20,. these curved portions preventing to a cer-: tainextent the escape of water laterally from the soles. so that amaxinuumtln'ust is secured from each stroke. I

Arranged upon the moccasin supporting surface of the sole is a stop 21forn1ed from a single bar of material this stop being fixed to the soleby brads or similar connectors and having its opposite ends projectingbeyond the edges of the sole and engaging the wings 20 and preventingmovement of the latter beyond the plane of the sole 10 during a stroke.

\Vhat isclaimed, is

A swimming shoe comprising a central sole portion tapering from the toeto the heel, projections extending from the toe and heel and formingshoulders at their meeting points with the body of the sole, two sideand terminates nearly at the outer edge of wings having curved outeredges curving to the upper face of the sole and extending from the toeinwardly toward the heel, the
